Bearing Application-FAG bearingsINA bearingsTIMKEN

Due to the high temperature steam passing through the rollers of the bearings used in the drying rollers of paper machines, the bearings must be in a high temperature environment. For this reason, the bearing may be peeled off early due to insufficient lubricant film formation, creep caused by aging due to long-term high temperature use, and
